At first I was thinking "man, these guys are barely moving--I'd zig and zag past this one and that one.." Then I remembered that it was in the wet and I'd probably have ridden just as conservatively. LOL
Great vid. For the newer riders watching this, as always, the key is to be smooth on/off the throttle and breaks. Traction is abundant in the wet (with proper tires) as you can tell by the cat ridding the wheelie at the start. The only time it gets sketchy is when there is patches of dry and wet, and the roost coming of the guys tire in front of you sux too!
